I downloaded the fancybox source code sample from http://fancyapps.com/fancybox/#license. Please look at the following short of script:
`
Thumbnail helper
<a class="fancybox_thumbs" data-fancybox-group="thumb" href="1_b.jpg"><img src="1_s.jpg" alt="" /></a>
<a class="fancybox_thumbs" data-fancybox-group="thumb" href="2_b.jpg"><img src="2_s.jpg" alt="" /></a>
<a class="fancybox_thumbs" data-fancybox-group="thumb" href="3_b.jpg"><img src="3_s.jpg" alt="" /></a>
` And below is the script
$('.fancybox-thumbs').fancybox({ autoPlay: true});
$.fancybox.open($(".fancybox_thumbs").get(), fancyboxOptions);
When page loaded, the fancybox would opened the overlay, the slideshow automatically switched from the first image to the second one, then it did not work anymore.
I did some research and google. I saw the site http://jsfiddle.net/GjNnj/3/ worked well. I checked it and I couldn't see anything wrong, same script, same version fancybox.
Any help is appreciated, thanks in advance
